Question

4. The hinge of a door is at a distance of 25 cm from the point of application of
force. How much force must be applied so that it produces the moment of force
of 4 Nm? ​

Answer 1

Answer:

hope it helps ☺️☺️

Answer 2

Answer:

Moment of force is also called Torque. As anidea, it is the turning effect to a force.

By definition,

Torque (about a point) = magnitude of force Xperpendicular distance (of this point) from the point of application of force.

Putting the given values here,

4 = F X 0.25 (in SI units)

=> F = 16 N

Hope it helps.
